Students attend the program for four hours each day after school, doing their homework, creating art, and playing sports.[6]

Howard launched the Thomas Howard Foundation in September 2009 to build partnerships and programs to enhance students' academic and athletic goals. The Foundation benefits youth who seek to excel in both education and organized sports activities. The signature scholarships and programs of the Thomas Howard Foundation include: The Annual Walk-On Scholarship; YFL Football Uniforms Scholarship Fund; the Are You Smarter than a 4th Grader program for school curriculum enhancement; and supporting the After-School All-Stars, providing programs that include academic support, enrichment opportunities, and health/fitness activities.
